Subject: [PATCH] conf: prevent NULL pointer access in
 virSecurityLabelDefsParseXML

When checking for seclabels without security models, def->nseclabels is
already set to n. In the case of an error def->seclabels is freed but
nseclabels is left untouched. This leads to a segmentation fault when
def is freed in virDomainDefParseXML.
